2021-12-14A better approach is to defined __CONCAT locallyTheo de Raadt
2021-12-14Sigh. This sys/cdefs.h is hiding use of __CONCAT in a non-C context.Theo de Raadt
Needs some other repairs first.
2021-12-13including sys/cdefs.h manually started as a result of netbsd trying toTheo de Raadt
macro-build a replacement for sccsid, and was done without any concern for namespace damage. Unfortunately this practice started infecting other code as others were unaware they didn't need the file. ok millert guenther

2021-11-14Delete all the no-op RELOC_GOT() macros and their uses.Philip Guenther
Annotate RELOC_DYN() on non-hppa as only used in lib/csu. Delete some inconsistent comments, adjust whitespace, and reorder mips64's archdep.h so that the ld.so/*/archdep.h files look (almost) the same. ok visa@ kettenis@
2021-11-12Add support for RELR relocations in the executable and share objects.Philip Guenther
This doesn't affect ld.so's self-reloc, which still requires DT_REL/DT_RELA ok kettenis@
2021-11-09Like most archs, riscv doesn't need resolution of JUMP_SLOT relocationsPhilip Guenther
in static PIE binaries: delete RELOC_JMPREL and HAVE_JMPREL there. ok kettenis@
2021-10-24For open/openat, if the flags parameter does not contain O_CREAT, theTheo de Raadt
3rd (variadic) mode_t parameter is irrelevant. Many developers in the past have passed mode_t (0, 044, 0644, or such), which might lead future people to copy this broken idiom, and perhaps even believe this parameter has some meaning or implication or application. Delete them all. This comes out of a conversation where tb@ noticed that a strange (but intentional) pledge behaviour is to always knock-out high-bits from mode_t on a number of system calls as a safety factor, and his bewilderment that this appeared to be happening against valid modes (at least visually), but no sorry, they are all irrelevant junk. They could all be 0xdeafbeef. ok millert

2021-09-13introduce /etc/bsd.re-config which can be used to configure the kernelRobert Nagy
using config(8); the contents of this configuration file will be fed to config(8) after kernel relinking is done, so on the next boot the new kernel will have all the configuration changes set by the user this comes handy if you still want to use KARL while making changes to the GENERIC kernel diff from Paul de Weerd with input from several developers
2021-09-02remove sys/param.h use, by replacing MAXLOGNAME -> LOGIN_NAME_MAXTheo de Raadt
and MAXHOSTNAMELEN -> HOST_NAME_MAX+1
2021-07-14Remove unneeded calls to tls_init(3)kn
As per the manual and lib/libtls/tls.c revision 1.79 from 2018 "Automatically handle library initialisation for libtls." initialisation is handled automatically by other tls_*(3) functions. Remove explicit tls_init() calls from base to not give the impression of it being needed. Feedback tb OK Tests mestre
2021-07-12Change the error reporting pattern throughout the tree when unveilBob Beck
fails to report the path that the failure occured on. Suggested by deraadt@ after some tech discussion. Work done and verified by Ashton Fagg <ashton@fagg.id.au> ok deraadt@ semarie@ claudio@
2021-07-07Hoist whole TLS initialization instead of loading the cert/key into memory firstRicardo Mestre
and setting them up later on, nowadays it's possible to do both steps in just one go through tls_config_set_{cert,key}_file(3) so use it and then init TLS. No functional change. OK kn@

2021-05-25program headers: do not rely on DYNAMIC coming before GNU_RELROkn
Except for some specific cases (thanks guenther) ELF mandates nothing but the file header be at a fixed location, hence ld.so(1) must not assume any specific order for headers, segments, etc. Looping over the program header table to parse segment headers, _dl_boot() creates the executable object upon DYNAMIC and expects it to be set upon GNU_RELRO, resulting in a NULL dereference iff that order is reversed. Store relocation bits in temporary variables and update the executable object once all segment headers are parsed to lift this dependency. Under __mips__ _dl_boot() later on uses the same temporary variable, so move nothing but the declaration out of MI code so as to not alter the MD code's logic/behaviour. Found while porting patchelf(1) from NixOS. OK guenther

2021-03-16On i386 don't attempt to map shared libraries in low memory whenKurt Miller
a large executable's .text section crosses the 512MB exec line. Executables that have MAXTSIZ > 64MB can map above the default 512MB exec line. When this happens, shared libs that attempt to map into low memory will find their .data section can not be mapped. ld.so will attempt to remap the share lib at higher addresses until it can be mapped. For very large executables like chrome this process is very time consuming. This change detects how much of the executable's .text section exceeds 512MB and uses that as the initial hint for shared libs to map into which avoids attempting to map into blocked memory. okay deraadt@

2020-12-26Fix a nasty mem leak in ld.so's own malloc. This was hard to diagnose, sinceOtto Moerbeek
malloc dumping and gdb do not help at all when studying ld.so. In the end it turns out ot be a simple merge error causing extra mmap calls. ok miller@ tb@
2020-11-28Add retguard to macppc kernel locore.S, ofwreal.S, setjmp.Sgkoehler
This changes RETGUARD_SETUP(ffs) to RETGUARD_SETUP(ffs, %r11, %r12) and RETGUARD_CHECK(ffs) to RETGUARD_CHECK(ffs, %r11, %r12) to show that r11 and r12 are in use between setup and check, and to pick registers other than r11 and r12 in some kernel functions. ok mortimer@ deraadt@
2020-10-26Retguard asm macros for powerpc libc, ld.sogkoehler
Add retguard to some, but not all, asm functions in libc. Edit SYS.h in libc to remove the PREFIX macros and add SYSENTRY (more like aarch64 and powerpc64), so we can insert RETGUARD_SETUP after SYSENTRY. Some .S files in this commit don't get retguard, but do stop using the old prefix macros. Tested by deraadt@, who put this diff in a macppc snap.

2020-10-11Don't skip file systems just because the parent fs is nodev and nosuid.Todd C. Miller
Fixes instances where a mount point uses the nodev and nosuid options but another file system mounted inside that hierarchy does not. OK schwarze@
2020-09-17afs, nnpfs, and procfs are no longer supported,Ingo Schwarze
so stop looking for them in mount(8) output; no functional change intended; OK millert@
2020-09-14Do not bother scanning file systems that are both nodev and nosuidIngo Schwarze
for SUID, SGID, and device files, implementing an idea that deraadt@ came up with based on a somewhat similar idea from millert@ after a loosely related comment from Rupert Gallagher on misc@. While here, minimally simplify the way mount options are parsed, hoping to make the parsing more readable and also more robust. OK millert@ deraadt@
